2 Claims. (Cl. 217-65) This invention relates to box construction and particularly to reinforcing structure for the corners and closures of the box.

The invention has been worked out more especially in connection with boxes used as foundation structures in the manufacture of luggage.

The invention has for its salient object to provide a box corner and reinforcing structure that can be economically manufactured and assembled and will be strong and rugged in construction.

Further objects of the invention will appear from the following specification taken in connection with the drawings which form a part of this application, and in which Fig. 1 is a top plan view of the body portion of the box and reinforcing strips showing the manner of assembling the parts; I

Fig. 2 is a vertical sectional elevation of the structure shown in Fig. 1;

Fig. 3 is a sectional elevation similar to Fig. 2 but showing one of the closures in place and showing the corners rounded off;

Fig. 4 is a perspective elevation of one of the corners showing one of the reinforcing strips in position;

Fig. 5 is a perspective elevation of one o-f the corners showing the longitudinal and transverse reinforcing strips in position and prior to the nishing off of the corner;

Fig. 6 is a plan view of one of the corners;

Fig. 7 is a sectional elevation taken substantially on line 7-7 of Fig. 6, looking in the direction of the arrows;

Fig. 8 is a perspective elevation of one of the corners after the closure has been secured and the corner has been rounded olf;

Fig. 9 is an end elevation of one of the longitudinal reinforcing strips; and

Fig. l0 is an elevational -view of the end of one of the longitudinal strips looking at right angles to the view shown in Fig. 9.

As shown in Fig. 1, the body portion of the box comprises sides 2i) and 21 and ends 22 and 23. This body portion is preferably formed of a plywood strip which is formed into the shape shown in Fig. l, the two ends of the strip being overlapped and secured together to form a closed structure. As shown in Fig. 1, the box illustrated has rounded corners A, B, C and D.

The corners of the box are recessed inwardly from the outer edges of the walls, as shown at 25, and the recesses are W-shaped, having vertical ends 26 and 27 and beveled bottoms 28 and 29.

The top and bottom corners of the box are reinforced by longitudinal strips 3i), 30 and transverse strips 31, 31. T he longitudinal strips are triangular in shape and have right angled sides 34 and 35 and a beveled connecting side 36. These strips are also beveled at their ends at 37 and 38.

The transverse strips 31 are also triangular in shape and have sides 40 and 41 disposed at right angles to each other, these sides being connected by a third side ft2.

The strips are positioned in the following manner.

The longitudinal strips are positioned with the vertical wall 34 positioned against the vertical wall of the side Ztl or 21. The side 35 of the longitudinal strip at right angles to the vertical wall or. side 34 is positioned horizontally and will be disposed against the closure 45 after the closure has been placed in position. The side 36 at its lower end rests against the beveled edge 29 of the recess 25.

It will be understood that both longitudinal strips 30, Sil are secured in the positions above described. There` after, the transverse strips 31, 31 are positioned with their vertical walls 41 against the inner surfaces of the end walls 22, 23 and with their sides 42 disposed against the beveled ends 36 of the longitudinal strips. This will position the sides or walls 40 of the transverse strips in the same plane as the sides 35 of the longitudinal strips Si), 3i). The strips, when so positioned, will be glued to the vertical walls of the sides and ends of the body member of the box and they will also be glued in the recesses, and the sides 42 ofthe transverse strips will be glued against the beveled ends 36 of the longitudinal strips. The transverse strips will project slightly beyond the vertical walls of the longitudinal strips, as shown at corners C and D in Fig. 1.

After the strips have been glued in position in the manner above described, the closure 45 is secured in position, being glued to the horizontal portions 35 and 40 of the strips 3d, 3h and 31, 31. Thereafter, the corners are rounded o in the manner shown in Figs. 3 and 8.

Because of the interlocking connections at the ends of the strips and the connection of the walls of the strips to the inner surfaces of the portions 2t), 2l, 22 and 23 of the body member and of the connection between the surfaces 35 and 4i) to the inner surface of the closure, a rm and rugged corner box structure is provided and this structure will not be damaged by rough usage.

Although one specific embodiment of the invention has been particularly shown and described it Will be understood that the invention is capable of modication and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.

What I claim is:

l. Box structure for reinforcing luggage comprising a body member having side and end walls and a cover panel, the said side and end walls merging into rounded corners, each of the said rounded corners having a recess exten-ding thereinto from the outer marginal edge of the walls, reinforcing strips adhesively secured to the side and end walls at the outer marginal edge thereof and to the cover, the ends of said strips extending into and filling said recesses and being adhesively joined in overlapping relation, the corners between the side and end walls and the cover and also the ends of the corners between the side and end walls being rounded by cutting to a smooth contour, the ends of the overlapping reinforcing strips, the side and end walls and the cover all combining at the rounded ends of each of the side and end wall corners to form a strong, continuous, rounded surface.

2. Box structure for reinforcing luggage comprising a body member having side and end walls and a cover panel, the said side and end walls merging into rounded corners, each of the said rounded corners having a recess extending thereinto from the outer marginal edge of the walls, parallel pairs of reinforcing strips adhesively secured to the side and end walls at the outer marginal edge thereof and to the cover, the bottom of each of said recesses having intersecting surfaces angled toward said marginal edge and forming beveled seats, the said reinforcing strips being right triangular in cross-section with the ends n thereof extending into and lling the beveled seats in said recesses, the right angled sides of said strips facing said walls and cover respectively and one of the parallel pairs of reinforcing strips having their ends beveled inwardly to join adhesively in overlapping relation the hypotenuse faces of the other parallel pair of strips, the corners between the walls and cover and also the ends of the corners between the side and end walls being rounded by cutting to a smooth contour, the ends of the overlapping reinforcing strips, the side and end walls and the cover all combining at the rounded ends of each of the side and end wall corners to form a strong, continuous. rounded surface.
